I wonder what happened- plane landed safely, but appears to have dropped engine nacelle parts on the way to KDEN.
I’d bet it’s actually shut down and just windmilling.Looks like that engine is still making power!

Could be, I would just be very surprised if the fuel supply wasn’t cut off in short order.Maybe, but that fire coming out of the combustion area might be still producing some thrust, albeit not much.

It's a damn good airplane. 747/757/777 are all fantastic birdsExciting day in the B-777 community, one of the best airliners ever designed. Maybe THE best one!
That’s heavy, man.CNN is funny at this point.... they are playing the mayday call and the announcer thinks that "United 328 heavy engine failure" is "heavy engine failure" rather than "United 328 heavy, engine failure." Understandable, but someone needs to mention in the earpiece the correct info.
This was a 777, not a 757.On another board with a ATC person, it turns out that the 757 isn't a "heavy". . . the history of that call sign with the 757 is a study in the FAA trying to find away to confuse things. It was a heavy in 2009 until it wasn't. Wake turbulence is strong with it, they had various models that were over the weight limit and others that weren't. So the FAA punted and just called them "large" and raised the weight limit above the 757 range! And then they increased the wake separation, until that got confusing so they dropped that too. So the pilot could be saying heavy engine failure or there is a possible factor of his being heavy to land, since the plane was barely out of Denver, bound for Hawaii (needless to say, glad that didn't happen two hours later. . . ). Or simply reverted back to being a 747 captain. . . I will grant him more than enough grace to say anything he wants at that point in the emergency!

When has that ever stopped anyone on POA or the internet in general? The amount of armchair aerospace engineers after any incident, especially one as dramatic as this one, is always astonishing.Knowledge of the subject matter at hand is helpful to conduct a conversation on said subject.
Just saying.
Maybe, but that fire coming out of the combustion area might be still producing some thrust, albeit not much.
A fan blade out event shouldn't result in the shedding of the entire cowling. It seems from available photos that the fan casing wasn't penetrated, so it appears it is still a "contained" failure from the perspective of rotating machinery not penetrating its respective casings, but obviously a catastrophic failure from the perspective of safety implications for both the aircraft and people on the ground. Will be a very interesting NTSB report to read once they get into the guts of everything.Well that’ll do it.View attachment 94196

I was actually referring as to why they had an engine failure. I agree with your statement.A fan blade out event shouldn't result in the shedding of the entire cowling.

The fan casing extends some ways upstream of the fan face before you get to the non-structural acoustic liner and cowling. I’d be pretty surprised if the broken blade shrapnel would work it’s way that far forward, And typically in blade off events the blade fragments either get caught in the fan exit guide vanes or exit out the back through the bypass nozzle, but it is possible I suppose (particularly if it was caught in the surge event that inevitably followed the blade our event). My guess is that the strong imbalance probably ended up shaking the cowling attachments to the point of failure but that’s just pure speculation. That shouldn’t happen but if the engine was left at high power with a heavy imbalance it might be possible. Again just speculation as a fun thought exercise.I wonder if the broken blade was "captured" by other blades and rotated long enough to slice open (off?) the front of the engine cowl?
They were taking the long way around.Note that debris fell in Illinois “Close to Chicago OHare Airport” Superb reporting.

Cheers.
Think of the ETOPS consequences at United
Fortunately, they won't have to go deep sea diving to recover the FDR and CVR.Wouldn't jump the gun just yet. First need to find out what failed and why. And as designed, the airplane kept flying and safely returned to the airport.
Should be under "freshwater" salvage laws, which mean that the property belongs to the original owner. We had to cite this when we had a marina, and someone "found" an outboard motor under water.Anybody know what the salvage laws are for airplane parts that fall on your property?
